Flower colour is mainly due to the presence and type of pigments. Pollinator preferences impose selection on flower that ultimately acts Knowing how pollinators perceive flowers with different pigments becomes crucial for a comprehensive understanding plant-pollinator communication evolution. Based space models, we studied whether main groups pollinators, specifically hymenopterans, dipterans, ...

Cabernet Sauvignon, Malbec and Merlot grapes were processed with prefermentative cold soak (CS) for 5 days followed by a short maceration time of (CS + 5d), or long 10 10d). CS did not affect the basic chemistry wines, nor improved anthocyanins, polymeric pigments total phenolics relative to Control wines (10 maceration). Wine tannins lowered in 5d 71 % (Cabernet Sauvignon) 29 (Merlot). CIELab ...

Hibiscus is rich in acids, anthocyanins, flavonols, oils, proanthocyanidins, and various pigments. It utilized for medicinal purposes, to improve human health, as a galactagogue stimulate milk production cows. Due its biofunctional activities, hibiscus oil has broad applications spanning different fields. This study analyzed the pH organoleptic quality attributes of three vegetable-based analog...

Anthocyanins are polyphenolic plant pigments associated with antioxidant and health-promoting properties. However, their application in the food industry is limited due to poor stability. The purpose of this study was encapsulate anthocyanin-rich bilberry (Vaccinium myrtillus L.) extract by freeze-drying investigate effects different wall materials contents on physicochemical bioactive properti...

The pomegranate fruit is a good source of bioactive compounds. The present study has investigated the biochemical and sensory characteristics of the arils of four Iranian commercial pomegranate cultivars namely Malase Shirine Saveh (MSS), Malase Torshe Saveh (MTS), Alak Shirine Saveh (ASS) and Agha Mohammad Ali (AMA) for several developmental and ripening stages during 45–180 days after fruit s...

Salicylic acid (SA) is a key molecule that alleviates abiotic stress in many plant species. In this study, the role of SA was examined to moderate lead (Pb) toxicity in the basil (Ocimum basilicum). The experimental design was a randomized complete block design with 4 levels of PbNO3; 0 (control), 100, 200 and 300 mg kg-1 of soil as the first factor, and the foliar application of SA at 3 levels...

Abstract Background Plants have remarkable diversity in petal colour through the biosynthesis and accumulation of various pigments. To better understand mechanisms regulating pigmentation Lonicera japonica , we used multiple approaches to investigate changes carotenoids, anthocyanins, endogenous hormones gene expression dynamics during transitions, i.e., green bud petals (GB_Pe), white flower (...

Jamun (Syzygium cumini L.) is a fruit rich in anthocyanins, an important group of natural pigments, with color ranging from red to blue, soluble water, highly antioxidant. Despite its great potential for use as dye, application challenge, due the instability these compounds environmental conditions processing and storage commonly used by food industry. Therefore, this study evaluated microencap...

Enological tannins are widely used in the winemaking process either to improve different wine characteristics (color stability, among others) or to compensate for low tannin levels. In this work, the influence of the addition of two different enological tannins, mainly composed of hydrolysable (ellagitannins) and condensed tannins, on the evolution of color and pigment composition of two differ...

Nitrogen is an integral element of foliar sprays during apple fruit formation. However, in red cultivars, the application may have adverse effects on color second stage development. The effect a low-dose urea was monitored ‘Topaz’ pomometric (fruit mass, firmness, total solids, starch content, skin color) and biochemical traits (primary metabolites, phenolic compounds, assimilatory pigments). T...
